Without getting too specific, he then revealed that Sony was eying a vague "Summer 2010" release, which hopefully means we'll see it before leaves start falling off trees next year.

However, those seeking to get their hands on Gran Turismo 5 sooner will find a PS3 demo on PlayStation Network next week.

To quote: "Interestingly, Hinojosa-Miranda had mentioned to me that he was traveling the U.S. in the coming week to photograph cars for Polyphony's reference material. With nearly 1,000 cars in the game, it's not that big of a stretch to think that they may still be working to flesh out the game's roster.

And while he wouldn't confirm how far along they were towards completing Gran Turismo 5 development, he did say this work wasn't necessarily for the current game.

"It's not for Gran Turismo 5 or a DLC release," he said, clarifying that it's constantly building on its reference material archives. After years of development and multiple Gran Turismo titles, how else do you think it's filling those garages but with non-stop research?

On the subject of DLC for the title, he said it was something it was considering, but had nothing to announce at this time."
